CORTECO 12018035B is an NBR cassette-type rotary shaft and wheel hub seal with an RWDR-K7 profile and dimensions 150x180x14.5/16 mm. The product is also identified by CORTECO commercial number 82018035. The complete designation, RWDR-K7 construction and dual height specification of 14.5/16 mm are important when selecting a replacement for a compatible axle, hub or industrial sealing arrangement.

The complete dimensions of CORTECO 12018035B are:
150x180x14.5/16 mm
where:
150 mm - inside diameter
180 mm - outside diameter
14.5 mm - first height
16 mm - second height
The complete 14.5/16 mm height specification is important when identifying this seal.
A replacement should not be selected only by comparing the 150 mm inside and 180 mm outside diameters.
CORTECO identifies this seal with the profile:
RWDR-K7
This is a cassette-type sealing design used in suitable shaft, axle and wheel hub arrangements.
A cassette seal is a more complex sealing unit than a conventional basic radial shaft seal. For this reason, CORTECO 12018035B should be identified using the complete technical specification:
12018035B + RWDR-K7 + NBR + 150x180x14.5/16 mm
This reduces the risk of selecting another seal with similar principal dimensions but a different internal construction.
The sealing material is:
NBR - nitrile butadiene rubber
NBR is widely used for technical sealing applications because of its good compatibility with many mineral oils and greases.
However, material compatibility is not universal. If the seal is exposed to an unusual lubricant, hydraulic fluid or other medium, compatibility with NBR should be verified.
A specific operating temperature range should not be assumed solely from the general properties of NBR. Actual suitability depends on the complete seal design, lubricant, speed and operating conditions.
A conventional radial shaft seal and an RWDR-K7 cassette seal are not the same construction.
The cassette design forms an integrated sealing system intended for a specific mechanical arrangement.
When replacing CORTECO 12018035B, check:
CORTECO part number
RWDR-K7 profile
inside diameter
outside diameter
both height dimensions
OE reference
axle or hub design
Matching only the dimensions 150x180 mm does not confirm interchangeability.
CORTECO 12018035B is catalogued for shaft and wheel hub sealing applications.
OE cross-references associated with this part number indicate applications in components and machinery from manufacturers including:
Carraro

OE numbers are useful for product identification, but final compatibility should always be confirmed against the parts catalogue for the specific machine, axle or hub.
The seal can be identified by two CORTECO references:
12018035B
and
82018035
The complete current product reference should be used whenever possible:
CORTECO 12018035B
The commercial reference:
82018035
can also be useful when searching technical catalogues or cross-reference databases.
The EAN associated with this product is:
3358960144485
This code can help identify the correct product and packaging in warehouse and purchasing systems.
For cassette seals, the complete dimensional specification is particularly important.
In this case:
150x180x14.5/16 mm
contains four relevant dimensional values rather than the simplified three dimensions commonly used for conventional radial shaft seals.
Ignoring the second height value can result in incorrect product selection.
Before installing a new cassette seal, inspect the complete bearing and hub arrangement.
Check in particular:
condition of mounting surfaces
bearing play
radial and axial hub play
shaft or axle condition
alignment
contamination
housing condition
possible cause of the original leakage
Installing a new seal without correcting excessive bearing play or mechanical damage can result in premature seal failure.
A cassette seal should normally be handled and installed as a complete sealing unit.
Its components should not be unnecessarily separated before installation.
A suitable installation tool should be used to apply force evenly to the correct surface of the seal.
Direct hammer blows can deform or damage the cassette.
The exact installation procedure should follow the instructions for the relevant axle, hub or machine.
The safest identification method is the complete manufacturer reference:
CORTECO 12018035B
If the original part number cannot be read, verify:
Inside diameter - 150 mm.
Outside diameter - 180 mm.
Height - 14.5/16 mm.
RWDR-K7 construction.
NBR material.
OE reference.
Axle or wheel hub type.
Construction of the removed seal.
Identical dimensions alone do not automatically confirm seal interchangeability.
The complete dimensions are:
150x180x14.5/16 mm
The specified sealing material is:
NBR
RWDR-K7 is the CORTECO profile designation for the construction used in this seal.
Yes. It is a cassette-type shaft / wheel hub sealing solution.
No. The complete 14.5/16 mm height, RWDR-K7 profile, material and manufacturer or OE reference should also be checked.
The commercial number is:
82018035
The EAN is:
3358960144485
Catalogues associate it with John Deere references including:
AL159594, ER047702 and RE204870
Compatibility with the exact machine must still be verified.
Cross-reference data include:
247546A1 and 87415728
for Case IH.
Yes. Cross-references include Carraro numbers:
047701, 047702, 133267 and 149702
No. CORTECO 12018035B uses an RWDR-K7 cassette construction and has the complete dimensional specification 150x180x14.5/16 mm. Matching the two main diameters alone does not establish interchangeability.
